Jan. 16, 1951 R. vY. ALLEN ANIMATD PICTURE LAMP Filed Feb. 6, 1946 'HIIIIIIT=== 'O I v 11 .4.

Ii i'S eiior :f int" Vi'f'e .a lmp'. ani de Structure. use es ,an amusemenv 'ofv display dev nally mounted for rotation therewith, projecting i upwardly as best seen in Fig. 4. A drum shaped shade 19 for the lamp constructed from opaque material is supported by a hollow central hub |1 to which are fixed three outwardly projecting spokes la attached to the shade |9 at its upper rim.

As can be best seen in Fig. 4, the hub I'l is `adapted to fit relatively loosely over the shaft |6 and rest on the armature |5. Thus it will be seen that as the motor M rotates, the shade IS is rotated thereby due to the frictional engagement of the hub IT with the armature 15, the shaft IG serving to center the shade with the motor. The

shade mounting just described is such that the shade 19 normally hangs in the Vertical position shown in Fig. 1, but if forcibly tilted may rock up on the lower edge of the hub ll, the relatively loose fit of the hub and the shaft being such that the shaft is not liable to be bent by such rocking action.

The zoetrope portion of the device is formed in the shade [9 near its lower edge and comprises a series of evenly spaced and relatively narrow slits 20 parallel to the cylindrical axisV and arranged in a band around the shade IS; and a series of animated cartoon pictures schematically -designated by the letters A, B, C, etc. imprinted on the interior surface of the shade |9, each picture falling between two successive slits 20 in the area designated generally by the numeral 2| in Fig. 3. o

An incandescent light bulb for the purpose of lighting the cartoon pictures and also for the purpose of providing general illumination is held in a conventional socket 21 fixed to the columnar support ll by means of a collar 26. Current for the light bulb 28 and for the motor |4 is provided through a pair of leads 30 which are led through the columnar support member H which is made hollow for that purpose. Leads 29 from the motor are connected in parallel with leads for thelight bulb 28 and the current supplied to both the motor 14 and the light bulb 28 is conw trolled by a switch (not shown) operated by a conventional pull chain 3|.

It will be seen that a lamp constructed as just described serves to provide general illumination in the conventional manner, light rays from the bulb 28 being directed downwardly and upwardly by the shade |9. It will also be seen that the light bulb 28 serves the additional purpose of furnishing relatively intense illumination for the cartoon pictures l i When the shade rotates clockwise, that is, in the direction of the arrows shown in Fg. 2, the cartoon pictures pass from left to right across the ba .z of the shade 59 and are scanned by the moving slits 20 which move from right to left across the front of the shade. Thus it will be seen that since the relative intensity of the light striking the cartoon pictures is very much greater than that striking the outside of the shade 19, the motion of the slits 20 lwill not be noticeable 4 against the relatively brilliant picture image. With this type of illumination, it is possible to view the animated picture from a point relatively clistant from the lamp at which point the definition is greatly improved overthat which is obtained when the eye is in close proximity to the slits 20.

One modification of my invention particularly adaptable to the device shown in Fig; 1 contemplates printing the animated cartoon pictures with luminous ink or paint. In this manner, luminous animated cartoons are produced which are visible after the light has been extinguished. It is desirable for this purpose to include a separate switch in order to extinguish the light without stopping the motor. A zoetrope operating on this principle is particularly effective in that the scanning slits are completely .invisible, the only visible motion after extinguishing the light being the motion of the cartoon itself.

Both of the embodiments illustrated and described herein are intended as lamps for nurseries and childrerrs playrooms. With the object of making these lamps more attractive to children, the motif expressed by the reclining figure |2 is repeated in the subject matter of the cartoon sequence. For example, the reclining figure |2 shown in Fig. 1 is decorated to represent the nursery rhyme character Little Boy Blue and to carry out this motif, the cartoon sequence may represent f'the sheep in the meadow or the cow in the corn." Many other adaptations and modificati'ons will of course occur to those skilled in the art.

While the apparatus described and illustrated herein is fully capable of attaining the objects and providing the advantages hereinbefore mentioned, it is merely illustrative of the broad scope of my invention as defined in the appended claims.

I claim:

1. In a display lamp, the combination of: 'a'

base; a Vertical standard fixed to said base and projecting upwardly therefrom; a horizontal member projecting laterally from said standard adjacent the upper end thereof; motor means having a Vertical upwardly extending axle thereon and mounted on said horizontal member; 'a tubular shade of substantially opaque material having spokes adjacent an upper edge thereof and being secured by said spokes to the axle of said motor means whereby to rotate about a vertical axis; a plurality of Vertical scanning slits formed in said shade adjacent the lower edge thereof, said slits being arranged in a circumferential band adjacent the lower edge of said shade; a plurality of pictures imprinted on the interior surface of said shade, one between each adjacent pair of saidslits, said pictures being adapted by progressive change in position of objects therein to produce the illusion of motion when viewed stroboscopically through said slits when said shade is rotated; and an electric light supported on said standard below said horizontal member, said light being positioned above the plane dened by said circumferential band "of slits whereby to provide relatively intense illuniination for said pictures as compared to the exterior surface of said shade, and whereby said pictures may be stroboscopically Viewed without substantial distraction by the motion of said shade.
